Step-3: Pre-installation configuration
Choose a Portal Server. Install the IT Analytics Portal software on its own, dedicated server. For performance reasons, the IT Analytics Portal software must not be installed on the same server as the Data Collectors. Root privileges are required for the Portal software installation tasks.
You will need to log in as a to perform the installation. Oracle requires that you are logged in as a . Logging in as a Domain Administrator is not sufficient for this installation. Refer to the Oracle web site for the requirement to install on Windows as a user who is a member of the server's local Administrator's group.
For new Portal installations, the minimum server memory requirement is 32 GB. Oracle database requires a minimum of 24 GB of memory. Portal installations will fail if sufficient memory resources are not available on the Portal server.
The Portal Installation software checks the following resources:
Total physical memory (physical + virtual) must be greater than 24 GB, otherwise Oracle will fail to start. Add more physical memory to the Portal server.
Windows Virtual Memory must be 24 GB or greater, otherwise Oracle will fail to start. Increase the size of the virtual memory if required ( > > > tab > > tab > click ).
Verify the OS of the Portal Server. Check that the OS is one of the certified operating systems listed in the Certified Configurations Guide.
Verify the Third-Party Software list.
Verify Microsoft Visual C++ Runtime libraries are installed.
IT Analytics installs Apache HTTP Server which has a dependency on run-time components of Visual C++ libraries. These run-time components are included in the Microsoft Visual C++ 2015 Redistributable Update 3 RC. This Microsoft distribution is available for download from www.microsoft.com. If this redistributable update is not installed prior to running the IT Analytics installer, Apache HTTP Server will not be able to run.
Note:
If you installed Microsoft Visual C++ 2015 after IT Analytics 10.3.xx was installed, and services are failing, you must manually install the Apache service using the following command:
C:\opt\apache\bin\httpd -k install -n "APTARE Apache"
Verify that sufficient disk space exists on the designated Portal Server. For the database file systems, the amount specified is the minimum to create the database. The database grows in size over the period of time. The growth of database dependents on various factors such as subsystems from which data is collected, type of systems collecting data from, retention periods for data(which is configurable), and so on.

Add itanalyticsportal.yourdomain and itanalyticsagent.yourdomain.comentries to your enterprise DNS Server. Both entries must resolve to the IP address of the Portal server. Also note that the last component of the domain must be one of the recognized root domains; for example, --not .
Verify that there are no other web servers--for example, IIS--running on the system.
The installer will set up the following system-wide environment variables and update the PATH environment variable:

ORACLE_HOME
C:\opt\oracle

The PATH environment variable will have the following path appended to the end of the current PATH:
